Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry behavioral disclosure. It communicates that this is a search operation returning CVE matches rather than full details, and it notes severity scope. However, it does not address pagination, default limits, filtering semantics, or read-only assurance, so the behavioral burden is only partially met.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
